Buying Guide
What to consider when choosing a high fat protein shake
- Calorie needs: If you’re aiming for weight gain, choose calorie-dense options like BOOST Very High Calorie drinks. For lean protein goals, opt for 30–40 g protein per shake without excessive calories.
- Protein type and quality: Look for shakes with complete proteins and essential amino acids. Whey-based options generally support fast recovery, while blends may offer sustained release.
- Flavor and convenience: Ready-to-drink forms are best for on-the-go lifestyles. Consider flavors you’ll enjoy regularly to maintain consistency.
- Digestive compatibility: Some shakes include fiber or prebiotics; others may be easier on sensitive stomachs. Check for added lactose if dairy sensitivity is a concern.
- Nutrient profile: Beyond protein, assess vitamins, minerals, and micronutrients that support immune health, bone health, and energy metabolism.
- Purpose alignment: Post-workout recovery, meal replacement, or weight gain each benefits from different protein-to-calorie ratios.
